Cas was sold into slavery to the European navy at the young age of 6, around 1602, when his deadbeat dad needed money to support his gambling addiction. Castiel blocked out a lot of his childhood and family. He couldn't even remember his last name.

     He would watch the sailors. He would watch them attack and take down enemy ships, he would study their books and journals, teaching himself to read, he would bring food to the prisoners who often spoke languages Castiel didn't understand; eventually he learned multiple languages: Spanish, French, and German. He would often listen to the sailors from below deck, he learned quite a bit.

He never left the boat. If he dared to talk back to any of the sailors they would punch him and if he risked to defy the captain he would surly be whipped like the others.

    The crew, on more than one occasion, quite frequently actually, would dock and go out to a nearby pub, and they came back, smelling like barrels of rum and whiskey with a whore on their arm.

        Castiel would often steal one of the extra sabre's they had on the ship. His favorite was one with a clean and smooth iron handle with a polished leather grip. It was evenly weighted too. He would go below deck, careful to avoid the sailors, and practice fencing. He would watch the opposing ships do it when the sailors stormed their ships. He played close attention and got pretty handy with it.

He didn't like his life and he believed he didn't have a soulmate, which was just fine with Castiel. But he would wake up with bruises on his back, and scars on his sides. One went all the way from the top of his left lung around to an inch above his bottom vertebrate. He often wondered where he got these but didn't intend to investigate.

    It was a lonely and dark life Castiel endured and he was interested in leaving it behind.
